Pathogens with the zoonotic potential to infect humans, such as Campylobacter jejuni, Campylobacter coli and Chlamydophila psittaci, can be found in feral pigeons (Columba livia). Given the high density of these birds in the public parks and gardens of most cities, they may pose a direct threat to public health.
A total of 118 pigeons were captured in three samplings carried out in 2006-2007 in public parks and gardens in Madrid, Spain. Standard haematological and morphological analyses were carried out on the pigeons. PCR was used to screen for the presence of Campylobacter jejuni, C. coli and Chlamydophila psittaci. Positive samples were confirmed by DNA sequencing.
The analyses demonstrated a high prevalence of Chlamydophila psittaci (52.6%) and Campylobacter jejuni (69.1%) among the birds captured. In contrast, Campylobacter coli was rarely detected (1.1%).
Pigeons in Madrid can carry Chlamydophila psittaci and Campylobacter jejuni. They may be asymptomatic or subclinical carriers of both pathogens.
具有感染人类的动物源性病原体，如空肠弯曲菌、大肠弯曲菌和鹦鹉热衣原体，可在野鸽（鸽形目鸠鸽科鸽属）中发现。鉴于这些鸟类在大多数城市的公园和花园中的高密度，它们可能直接威胁公众健康。
2006-2007 年，在西班牙马德里的公园和花园中进行了三次采样，共捕获了 118 只鸽子。对鸽子进行了标准的血液学和形态学分析。PCR 用于筛选空肠弯曲菌、大肠弯曲菌和鹦鹉热衣原体的存在。阳性样本通过 DNA 测序进行确认。
分析表明，所捕获的鸟类中鹦鹉热衣原体（52.6%）和空肠弯曲菌（69.1%）的流行率很高。相比之下，很少检测到大肠弯曲菌（1.1%）。
马德里的鸽子可能携带鹦鹉热衣原体和空肠弯曲菌。它们可能是这两种病原体的无症状或亚临床携带者。
